I have to say I have some sympathy with that view. Much though I love
OS X as a desktop OS, I have to wonder why anyone would jump through
hoops building a cluster running just Darwin, when they could probably
have done it much more easily, and with much more community support,
if they used Linux... It just seems like a lot of extra pain and
difficulty for no tangible benefit.
